Hey all, just after some help..

I have been planning on doing an upgrade to all the undercar parts (arms, links etc..) for a while, as I think some are a bit damaged from age/hard driving/thrashing and a minor crash in the last few years (myself, but apparently an old owner had a minor bit of damage as well), anyway I think it's time for an upgrade.

What my question is is exactly what parts are there under the car in terms of links, arms, etc...

I understand that there is front upper and lower and rear upper and lower control arms, traction rods etc. etc. but i've just been a bit concerned cos i'm using RHDJapan as a parts supplier, but I'm actually unsure what to buy as from what i can gather, parts go under different names?

Basically I want to upgrade everything for adjustability, and also to run it round a track every so often, so exactly what parts are under there?

Oh, and I have the HICAS locked if it helps..

Any help appreciated.

I'll start it off with

Front upper and lower control arms

Rear upper and lower control arms

unfortunately....that is a big question. the good news is, if you do go through with it you will probably be amazed with how much better the car feels.

Front Suspension

Springs

Shocks. There is a rubber bush at the top and bottom. In a skyline this does not have a direct effect on the suspension geometry unlike in strut suspension. It can still cause a "knock" noise

Sway Bars. There are 2 ball joints at each side and 2x "D" bushes that clamp it to the subframe. You can get kits for these from many suppliers.

Upper control arm. I am not familiar with the 33 GTST upper arm. In a 32 GTR it has bushes which flog out very easily. I replace mine about twice a season. You can get them locally.

Lower control arm. Also not really familiar with 33 gtst. On a 32 GTR it has 2 ball joints, 1 inner and 1 outer. Neither are readily available except from nissan (and expensive). The good news is they last well

Caster Rod. Has large bushes at the chasis end. Replacements readily available locally, or use a replacement arm with rose joints

Steering rack. Has 2 bushes holding it to the car. Has inner and outer "tie rod ends", both of which can wear. You can get non-genuine ones locally. There is a ball joint at the hub that the tie rod end bolts to, it also wears.

Rear. The front was easy.

Springs.

Shocks. Same as the front. A bush in the strut top, and at the bottom of the shock.

Sway Bars. Similar to the front - D bushes attaching it to the car. links with 2 ball joints.

Upper Control Arm. Bushes at the inner and outer end. Rose joint options to replace the arm

Upper Traction Arm. Bushes at the inner and outer end. Rose joint options to replace the arm

Lower Control Arm. 2 Bushes at the inner end. Ball joint at the outer end. I think they are hard to find in rose-joints for 33 Gtst

Steering Rack. Inner and outer rack ends, some are available locally. Also ball joints at the hub.

Brands to look at: Whiteline, Whiteline plus (noltec), Superpro make "nolathene" bushes which are a fair bit harder than factory, and are often adjustable. You can also get nissan or nismo (similar but a little harder) but very expensive. Or you can replace the whole suspension arm with one of the china aftermarket arms which have "rose-joints" at each end. These are tighter, harsher and will wear out sooner, but are cheap and accurate.

Driveline - cv joints in each driveshaft, tailshaft CV joints and uni joint. Gearbox mount. Engine mounts. Diff bushes for front and rear mounts.

I have replaced every one of the items above on my race car....and it was worth it. Handling is much more precise and predictable as you would expect for 20yo parts.

  • Like 1

thanks a ton Duncan, that really helped me out heaps... It just doesn't handle like it used to since it was crashed, steering seems a tad sluggish and unresponsive. The mechanic is going to have a good solid look over it all..

Any recommendations for tie rods or anything like that? I had a look through RHDJapan, and there are tons of them: Kazama, Nismo, GT-One Motorsports, Cusco, URAS, Tein, Ikeya Formula (Rather exxy but apparently the best in terms of quality), some by Powered by Max, Moonface Racing, Yanack or Trust!!

I was thinking already about whiteline bars, and upgrading bushings where possible, the car is reasonably low already (100mm from the ground, at legal minimum height), I just want it to handle a tad better as it was partially why the crash occurred (that and me being a dickhead in the wet, learnt my lesson not to do that on shitty tyres anymore!!)

Also, roughly how much did you end up spending, from rough guesses it would have been between 2 and 3 grand? or a bit more?

Also, just curious as to what a transverse arm is classified as? it's a relatively straight bar but im just unsure whether it's a control arm or something like that?

I'm brilliant at motor stuff but when it comes to handling i'm a hopeless case!!!

Transverse arms are usually referred to as control arms. The front has two - upper & lower.

The rear has three. A lower arm and two upper arms. The front upper arm is usually known as a the traction arm/rod.

The thing in the previous post is a castor rod and or tension rod.

yeah DJR81 is on the money, nismo does most of these parts upgraded through RHDJapan but only the control/transverse arms, otherwise for tie rods and such I'm probably going to have to go non-Nissan.

Thanks for the help though

Going back to the original post - you said you wanted to upgrade everything for adjustability. A couple points

1. You dont really need to.

2. Much of the Nismo stuff doesn't adjust anyway.

If stuff is flogged out by all means replace it. But replacing stuff for the sake of it is expensive.

Nismo stuff is here:

http://www.nismo.co.jp/en/products/competition/lb/skyliner33.html

... It just doesn't handle like it used to since it was crashed, steering seems a tad sluggish and unresponsive.....

I wold look at the steering rack itself being bent. especially if it doesn't return to centre very well.

The list I posted in adjustable aftermarket bushes would be $3-6k depending on if it is yourself or a workshop doing it. A huge job to do yourself with lots of findly and tricky jobs

If stuff is flogged out by all means replace it. But replacing stuff for the sake of it is expensive.

I agree....but most stuff is flogged out after 15 years and 150000klm

Thread revival from the dead, has anyone used the powered by max gear? Or more to the point the solid subframe risers listed on their site here http://www.gtfactory.jp/cms/page.php?17

How would the solid bushes compare to whiteline plus rubber replacements on a sunday driver/circuit semi-timer? I understand there would be a heap more noise and vibration feel coming through, but would they have any other effect?

sloth - just noticed your post after trawling thru for the list of parts, I can't vouch for anyone using Powered by Max but I do hear they're good (i'm buying a few of their shirts, part of my new wardrobe update = tons of obscure JDM brands! :P)

as for the risers, I have the subframe bushing things the solid ones that slip either side and they make a definite difference, more noticeable if you don't have ridiculously over-stiff springs like mine (they're on the list after paint/panel and some fat Work rims :D) but it makes the arse end much more predictable if you're getting it out a bit, that with Hicas lock definitely is a noticeable change

Raysboostin - Try this site, it's a HICAS lock bar with modified rack ends for it as well, try this bad boy out for size :

http://www.driftworks.com/shop/driftworks-total-hicas-eliminator-kit-for-nissan.html

This is the full kit with poly bushes, and the arms. It says for S13/14 or whatever on the site but it will fit anything with HICAS :)

I'm ordering a set in the next few weeks, full kit comes to around $400 with freight from britain

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
